On the tulip flame phenomenon

Web1 de fev. de 1992 · In the early stages of flame propagation, the flame behaves in a similar manner for different boundary conditions, that is, the flame develops a tulip shape that further evolves into a distorted tulip flame (DTF) through Rayleigh-Taylor instability arising from acoustic-flame interaction. Web11 de jan. de 2024 · The tulip flame phenomenon occurs when a premixed flame spreads in a tube (or duct) that is closed at both ends or only at the ignition end. Therefore, this phenomenon can also occur in half-open tubes.
